This innovative half-mask respirator features MSA's patent-pending, single-loop head harness and user-friendly design. Easy to don, doff, or drop down, it contains just three major components, making it extra easy to clean. The one-piece MultiFlex nose cup is made of soft, smooth, co-molded silcone and rigid plastic for a unique combination of durability and comfort.

With more than five million units sold, the upgraded 3S Full-Facepiece Respirator offers safety, comfort and durability. The face blank is made of a softer rubber compound (and also yellow silicone in another option) and has a wide sealing frame and deeper chin stop for a snug, comfortable fit. The lens is made of impact-resistant polycarbonate (and silicate-coated glass and Triplex glass in other options) and offers a wide field of vision for excellent viewing. The harness allows for quick donning and removal and achieves a pressure-free fit in combination with a protective helmet. The inner mask allows for optimal air flow and eliminates lens fogging. The mask comes in more than 50 different versions, allowing users to find the perfect mask.
